I hope the Climate Activists are proud of the effect their lies are having on the younger generation

Roger B

If this survey is real the messages these young people are receiving are completely wrong.

We need to reduce our impact on our planet but CO2 is a complete red herring. The current ECS (temperature increase for a doubling of CO2 in the atmosphere) is centred around 3°C (IPCC AR6). The 2°C will destroy civilisation is simply made up.

    When people came to do the insulation in 2010, there were three issues: (1) layingrockwool  insulation on the flat floor of the loft, to insulate living space from roof; (2) blowing pellets into wall spaces, where there are double walls; (3) blowing flock into the eaves/sloping roof spaces. 

    Odd that not all of these should be standard in British procedures.

    Well if you do that last one here you will probably have condensation in the loft and then wet rot of the timbers.  If you insulate the sloping section (rafters) then a bit of experiment will show you must ensure free airflow between the back of the roof tiles and the outer side of the insulation - so in my case I cut polyurethane foam sheets to be a jam fit, but left ~ 40-50mm between that and the back of the tiles so there is an open void from from eaves to ridge.  the loft is then warm and dry. There is then no real need for the ceiling rockwool. Cavity wall insulation is worth it though.

    It is not helped by the fact that defined thermal standards and mandatory insulation first entered the UK building regs in 1984, and then it took quite a while to become standard practice for local builders. (so my parents extension, 1983, was still done in solid walls, to match the rest of the house. At the time the building control inspection chaps were quite happy with that. They would not be nowadays…)
